Life at TumiTrust

We build programmable trust infrastructure—the layer banks, governments, and global institutions will depend on for decades. That requires craftsmanship, Ubuntu, and teams who think in systems.

What we optimize for

Our values

  • Craftsmanship — correctness, observability, and longevity over shortcuts.
  • Ubuntu — trust is relational; we build for communities, not silos.
  • Configuration over customization — institutions onboard without forks.
  • Explain before enforce — every score carries provenance.
  • Global ambition, local sovereignty — national deployments by configuration.

How we build

Principles & philosophy

Engineering Principles

We follow the PTI Constitution: configuration over customization, everything is a trust event, explain before enforce, tenant boundaries are sacred.

Every PR is checked against whether it moves PTI closer to becoming the world's trust infrastructure.

Platform Philosophy

PTI is infrastructure with protocol characteristics—institutions integrate via stable APIs and registries, not custom code. We evolve through strangler extraction and GitOps, never greenfield rewrites.

How We Work

Async-first documentation, weekly architecture office hours, quarterly DR drills, and honest readiness scorecards. We measure adoption velocity, not feature count.

Hiring Values

We hire for craftsmanship, humility, and systems thinking. We value evidence over credentials, explainability over hype, and decades over quarters.

Infrastructure Mindset

If PTI became the world's trust infrastructure, would this design survive? That is the question behind every technical decision.
